Description

"COMPOSITE ARTICLE" The present invention relates to a composite article comprising an outer layer of a microfibrous, nonwoven material, useful in the field of interior decoration and of transports.
Microfibrous, non-woven materials, generally constituted by polyester or polyamide microfibres, e.g., microfibres of nylon-6, in a polyurethane matrix, are known in the art. Among these materials, the one formed by poly-(ethylene terephthalate) microfibres in a polyurethane matrix constitutes a valuable, widely used, product, used in particular in garment industry, thanks to its excellent characteristics of appearance, hand, light-weight, velours and to its fastness to light and to nitrogen oxides in the atmosphere.
According to the instant finding, such microfibrous, non-woven materials are coupled with a cloth in order to supply novel composite materials which with their extremely good aesthetical appearance combine high mechanical properties, so as to find t h i r u 5 e i n the se-tor of interior decerati, 36 and in the sector or transports.
In accordance therewith, the present invention relates to a composite article comprising an outer layer of a microfibrous, non-woven fabric, and an inner layer of cloth. Advantageously, the coupling is carried out by means of the "multidot" technique, or by means of the flame technique, of the film technique or of the "liquid bonding agent" technique.
According to a form of practical embodiment of the present invention, the microfibrous, non-woven material, perforated with holes of different shapes, is coupled with an either dyed or printed cloth, so that articles are produced which, besides their mechanical strength, display particular aesthetical effects.
In the instant invention, by the term "microfibres" those fibres are meant which have a count comprised within the range of from 0.01 deniers to 0.40 deniers, and preferably of the order of from 0.08 to 0.15 deniers.
The microfibrous, non-woven material formed by microfibres of poly-(ethylene terephthalate) in polyurethane can be obtained by means of a process generally comprising the following steps: * a non-woven fabric made from microfibres of poly (ethylene terephthalate) is impregnated with a polyurethanic elastomer; * said polyurethanic elastomer is coagulated in order to form a composite, microfibrous sheet; * said composite, microfibrous sheet is ground in order to form a raw, microfibrous, non-woven fabric; and * said raw, microfibrous, non-woven fabric is dyed in order to produce a dyed end produc-'..
The non-woven fabric of microfibres of O ty- (ethylene terephthalate) can be obtained in its turn from a raw felt of staple fibre, constituted by microfibres of poly-(ethylene terephthtalate) englobed in a polystyrene matrix, with said raw felt being submitted to needling in order to produce a needled felt, with said needled felt being treated first with an aqueous solution of polyvinyl alcohol and then with perchloroethylene, so as to dissolve the polystyrene matrix and recover the non-woven fabric of microfibres of poly-(ethylene terephthalate).
The microfibrous, non-woven material obtained in that way shows excellent characteristics of appearance, hand, light-weight, velours, fastness to light and to nitrogen oxides in the atmosphere.
In particular, such a non-woven, microfibrous material displays characteristics generally falling inside the following ranges: * thickness (ASTM D-l910) : from 0.5 to 0.8 mm * weight per unit surface area : from 150 to 250 g/m2 * tenacity (ASTM D-1682) longitudinal : from 4.5 to 9.0 kg/cm transversal : from 3.0 to 7.0 kg/cm * elongation CASTS D-1682) longitudinal : from 65 to 85% transversal : from 90 to 130ç/ * tearing strength (ASTM D-1424) longitudinal : from 0.6 to 1.6 kg transversal : from 0.6 to 1.G ko * abrasion resistance (ASTM D-1175) : from 7,000 to 25,000 cycles * permeability : from 1,500 to 4,000 litres/hour.
According to the present invention, such a microfibrous, non-woven material, or similar microfi-brous, non-woven materials, possibly perforated, is(are) coupled with a cloth in order to obtain novel articles which combine valuable aesthetical properties with good mechanical characteristics, so as to be suitable for use in the sector of interior decoration and of transports.
The cloths used for that purpose are knitted fabrics, or cloths of various kinds, such as cotton, polyester, nylon, viscose and so forth, or blended fibres with compositions selected as a function of the desired end properties. These cloths can be raw, or dyes or printed. The dyed or printed cloths, with various decorative patterns, coupled with the microfibrous, nonwoven material, yield end articles which are particularly pleasant from the aesthetical viewpoint. Furthermore, either, or both of the constituents of the composite article can show flame retardant characteristics.
The composite articles according to the present invention are useful in the sector of interior decoration and in the sector of transports, and can be used in order to coat settees, office armchairs, car seats, and the like.
In the case of a non-perforated microfibrous, nonwoven material, the coupling With the cloth can be advantageously carried out by means of the following "multidot" technique.
The cloth, in the forum ot previously prenared bobbins, is fed by means of an unwindino unit to t o a machine of Carat sc h type, which consists of an engraved and heated roll, inside whose hollows the powder of the bonding agent, of polyamidic or polyester type, is fed.
By the effect of the controlled heating, the roll deposits, by contact, "dots" of bonding agent onto the cloth. The so obtained cloth with the deposited dots of bonding agent is made run through an I.R. oven, inside which the dots of the bonding agent are caused to melt, and then said cloth with dots of molten bonding agent is coupled with the microfibrous, non-woven material by operating on a calender with rubber-coated rolls and under a controlled pressure.
When a perforated microfibrous, non-woven material is used, the bonding agent is applied to said material rather than onto the cloth. More particularly, such a perforated material is fed, on a conveyor belt constituted by a net belt, to a distributor of "sieve" type, which makes it possible the powder of the bonding agent to be evenly distributed, whilst that portion of the powder which falls inside the opening of the hole, passes through the net which constitutes the conveyor belt and is collected in the underlying region. The microfibrous, non-woven material, still kept on the conveyor belt, is then fed to an oven with a carefully controlled temperature, in order to melt the bonding agent. The coupling with the cloth is carried out by means of a calender on the microfibrous, non oven material as soon as this latter Leaves the oven.
The microfibrous, non-woven material can be perforated in continuous by means of presses equipped with punches mounted on a plate. The "chips" are expelled by means of an air jet.
The present finding is furhter illustrated by means of the following experimental examples.
Example 1 The microfibrous, non-woven material is used, which -is marketed under the trade name MASTER (registered mark) by the company ALCANTARA, and has the following characteristics: * thickness : 0.80 mm * weight per unit surface area : 230 g/m2 * tenacity Longitudinal : 8.6 kg/cm transversal : 5.8 kg/cm * elongation Longitudinal : 81% transversal : 12.9 * tearing strength longitudinal : 1.52 kg transversal : 0.78 kg * return longitudinal : 1.8X (at 400C) transversal : 0.7% (at 400C) * abrasion resistance : 19,800 cycles * permeabiLity : 1,700 Litres/hour.
